ASSIGNOR OF ONE-HALF TO GEORGE W.

HOWE, OF CINCINNATI, OHIO.

WINDOW-SASI-I.

To all whom it may concern:

Be it known that I, JOHN S. HOPPER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in WVindow- Sashes, of which the following is a specification.

This invention comprehends certain new and useful improvements in window sashes of that type that are mounted for a laterally swinging movement as well as the customary vertically sliding movement.

One of the objects of the invention is, in a sash structure of this character, a brace or bracket eye arranged to hold a full length rod at the middle thereof, the sash being mounted to swing laterally on such rod, in such a manner as to prevent any ordinary strain upon the rod such as is incidental to the outwardly swinging movement of the sash, from bowing the rod and getting it out of shape, while in addition to this function, the said rod supporting bracket is mounted to slide to a limited extent so as to provide for a certain manipulation of the sashes to effect the complete opening of both of them as will be hereinafter more fully described.

With these and other objects in View, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings in which:

Figure 1 is an elevation of a window embodying the improvements of my invention; Fig. 2 is a horizontal sectional view thereof; Fig. 3 is a vertical transverse sectional view, the section being taken through both sashes, and Fig. 4: is a perspective view of one of the full length rods upon which the sashes are mounted to slide and turn, together with the sliding bracket which is so connected to the rod that it is permitted to move vertically to a limited extent for a purpose which Will be hereinafter fully specified.

Corresponding and like parts are referred to in the following description and incli- Specifieation of Letters Patent.

Application filed July 7, 1908.

Patented June 7, 1910.

Serial No. 442,315.

cated in all the views of the accompanying drawings by the same reference characters.

Referring to the drawing, the letter A designates a lower sash, and B an upper sash of a window equipped with the improvements of my invention. Each sash is mounted for a laterally swinging as well as a vertically sliding movement and to this end each sash is provided at one edge with eyes 1 that are mounted to slide and turn upon rods 2 and 3 which extend the full length of the window frame.

In sashes of this type, as is well known, it is desirable to swing both of the sashes inwardly, at times, and one above the other for the purpose of washing the window panes or the like, and as in the closed position of the sashes their meeting rails of course overlap, it is necessary that the lower sash be fully raised and the upper sash fully lowered before this complete inwardly swing movement can be effected. It is also necessary that some provision be made for moving the inner sash upwardly, so that its lower edge will clear the upper edge of the upper sash when the lower has been moved downwardly to the lower limit of its movement, and for this purpose I preferably form a well a in the upper end of the window jamb or lintel, so that the lower sash may be first moved upwardly into the well to permit the upper sash (at the lower limit of its movement) to be swung inwardly to the full extent, after which the lower sash may be lowered to a slight extent to clear the upper edge of the window frame and also swung inwardly to the full extent.

One of the objects of my invention as above stated, is to prevent these rods 2 and 3 from becoming bowed or bent by the strain imposed upon them when the sashes are swung inwardly, and I have accordingly provided bracket eyes which are secured to the window midway the upper and lower ends thereof. Obviously in order to secure the proper bracing effect this bracket must be located at about the meeting rails of the two sashes. Hence it is also evident that the bracket eye for the rod 2 of the lower sash must be capable of sliding upwardly when it is engaged by the lowermost eye 1 of such sash, when the sash is lifted high enough to provide the clearance just men- 'gsa I tioned, for theinwardly swinging movement of the upper sash. In order to secure this result, the bracket eye for the lower sash A designated 5 and best illustrated in Fig. 3 is provided with a shank or stem 6 which terminates in a head 7 which is mounted for a limited vertical movement in a slot 8 formed in a jamb plate'9 secured by screws or similar fastening devices to one of the jambs of the window frame. In order that I the head may enter into the slot 8, the said slot is formed at one end with a widened portion 10 as clearly illustrated in the drawmg.

, From the foregoing description in connection with the accompanying drawing, the operation of my improved window sash will be apparent. In order to fully open both .the lower and upper sashes, and then swing them both inwardly and fully apart to a corresponding extent, the lower sash is first raised up into the well l and the upper sash B is lowered as 'far as possible. Obviously inthe upward movement of the lower sash to clear the upper rail of the upper sash, when the latter is at the lower limit of its movement, the eye will strike the bracket eye 5' and move the same upwardly to a limited extent on the rod 2 after which both sashes can be swung inwardly one as far as the other. This upwardly swinging movement of the bracket eye 5 does in no wise detract from the bracing effect thereofon the rod 2, as the eye will effectually prevent the rod from becoming bowed in the strain of swinging the lower sash inwardly.

Having thus described the invention, what is claimed as new is:

1. The combination with a window frame and the upper and lower sashes thereof of vertically disposed rods mounted in the lower rail thereof will provide a clearancefor the upper rail of the upper sash when the latter has been moved downwardly to the lower limit of its vertical sliding movement, the sashes being provided with eyes mounted upon said rods whereby to provide for the laterally swinging movement of the sashes on the rods, a vertically slotted plate secured to the window frame contiguous to the meeting rails of the two sashes, and a bracket slidingly mounted on the rod 'for the lower sash and having a sliding engagement in the slot of said plate as and for the purpose set forth. V

2. The combination with a-window frame and the upper and lower sashes thereof, of vertically disposed rods mounted in the frame and extending from top to bottom thereof at one-side of the frame, the sashes being provided with eyes mounted to slide and turn on said rods, a a-mb plate secured to the window frame at themeeting rails of the sash, said plate being formed with a vertical slot the upper end of which is widened to provide an entrance opening, and a bracket eye mounted to slide on the rod of the lower sash and formed with a head adapted to slip through said entrance opening back into the plate for a vertical movement in the slot thereof.

In testimony whereof I afiix my signature in presence of two witnesses.
